Answer:
Cell X
Explanation:
Prokaryotes do not have a nucleus or any other membrane-bound organelles (including chloroplasts). So cell X is a prokaryote.
Answer:
a. preventing the cross-linkage of NAM subunits
Explanation:
The bacterial cell wall is made of peptidoglycan which is a polymer of alternating N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) residues. The NAM residues are crosslinked to impart additional strength to the cell wall.
Most of the antibiotics that target the cell wall synthesis in bacteria inhibit the enzyme of transpeptidation which in turn cross-links the NAM residues of the polysaccharide chains of the bacterial cell wall. Examples of these antibiotics include penicillins and cephalosporins.
I would think vinegar if it was dissolved in vinegar
Hard water contains mineral ions basically the calcium and magnesium ions.
The presence of hard water often considered a negative thing as it is associated with a number of issues related to plumbing, water storage as well as cleaning and maintenance.
Hard water leads to clogged pipes due to the deposition of ions on the surface of water conducting pipes. This hindrance also degrades the quality of equipment used for water storage and heating e.g. geysers.
The hardness of water can either be temporary or permanent depending on the type of ions present in it. Temporary hard water contains calcium and magnesium ions whereas Permanent hard water contains anions like the sulfate ion.

Below are the choices that can found elsewhere.
<span>A) 3/16
B) 1/8
C) 9/16
D) 1/2
E) 1/4
F) not enough information given
The answer is A </span><span>because the two traits are determined by unlinked genes, they assort independently. As a result, you need to use the multiplication rule to calculate the probability of agouti brown offspring (A_ bb) from AaBb parents. The probability of A_offspring is 3/4, and the probability of bb offspring is 1/4. The combined probability is therefore 3/4 x 1/4 = 3/16.</span>
